Connect Your Erba EC90 to Any HIS or LIMS

The Erba EC90 is an electrolyte analyser (Na, K, Cl, and related ions) that uses an unusual hybrid protocol: ASTM E1381 framing carrying HL7-style OBX/OBR records.

The EC90's hybrid protocol trips up generic middleware — it frames like ASTM but its records read like HL7. LISBridge includes a dedicated EC90 reader built against the EC90 LIS interface specification, so electrolyte results land in your HIS automatically and correctly.

How LISBridge Connects the Erba EC90

01

Connect your instrument

Plug in via RS-232 or point it at LISBridge over TCP/IP. Auto-detection identifies the instrument and loads the correct parser — no manual selection.

02

Parse the data

LISBridge reads the ASTM E1381 (hybrid HL7 records) stream in real time. Every result message is decoded — field by field — into structured data.

03

Validate results

Each result is checked for completeness. Duplicates caught. Malformed messages flagged. Only clean data moves forward.

04

HIS receives clean data

Validated results reach your HIS automatically — as HL7 or direct format. Stored locally too. No manual entry required.

Erba EC90 — Frequently Asked Questions

What protocol does the Erba EC90 use?

A hybrid: ASTM E1381 low-level framing with H/P/L records, but HL7-style OBX/OBR result records inside. LISBridge implements this exactly per the EC90 LIS Interface specification — no protocol converter needed.

What parameters does LISBridge extract from the EC90?

The electrolyte panel the EC90 reports — sodium (Na), potassium (K), chloride (Cl), and related ionic measurements — with units and flags preserved.

Why do other middleware products fail with the EC90?

Generic parsers assume a message is either ASTM or HL7. The EC90 is both at once, so pure-ASTM parsers reject its records and pure-HL7 parsers reject its framing. LISBridge's dedicated reader handles the hybrid natively.

How long does EC90 setup take?

Under 30 minutes. Connect the RS-232 cable, open LISBridge, and the EC90 is identified from its device ID automatically.
